Description

The ’HC138, ’HC238, ’HCT138, and ’HCT238 are high-speed

silicon-gate CMOS decoders well suited to memory address

decoding or data-routing applications. Both circuits feature

low power consumption usually associated with CMOS

circuitry, yet have speeds comparable to low-power Schottky

TTL logic. Both circuits have three binary select inputs (A0,

A1, and A2). If the device is enabled, these inputs determine

which one of the eight normally high outputs of the

HC/HCT138 series go low or which of the normally low

outputs of the HC/HCT238 series go high.

NOTE: When ordering, use the entire part number. The sufﬁxes 96

and R denote tape and reel. The sufﬁx T denotes a small-quantity

reel of 250.

Two active low and one active high enables (E1, E2, and E3)

are provided to ease the cascading of decoders. The

decoder’s eight outputs can drive ten low-power Schottky

TTL equivalent loads.

CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
